In Greer’s wistful new novel, a middle-aged writer accepts literary invitations around the world—making his way from San Francisco to New York, Mexico, Italy, Germany, Morocco, India, and Japan—so that he will have an excuse not to attend the wedding of a long-time lover. Arthur Less is not known primarily for his own work but for his lengthy romantic association with a Pulitzer Prize–winning author, an older man who was married to a woman when their liaison began, and he believes himself to be the butt of many cosmic jokes and that he is “less than” in most equations. This is partially proven true, but not entirely. And even in Less’s mediocrity, when aided by a certain amount of serendipity (and displayed by the author with ironic humor), he affects people. Greer (The Confessions of Max Tivoli), an O’Henry-winning author, writes beautifully, but his occasionally Faulknerian sentences are unnecessary. He is entirely successful, though, in the authorial sleights of hand that make the narrator fade into the background—only to have an identity revealed at the end in a wonderful surprise.
